About this 1.31ct natural radiant diamond

This 1.31ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7528568082. Listed at 6 retailers as of November 3, 2026, with prices from $3,759 to $8,165, a $4,405 spread on the same certified stone. NZ Jewellers lists it at $8,165. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
